With the main burner in operation, paint all pipe joints (including adapters) and gas control inlet and outlet with rich soap and water solution. The servo pressure regulator monitors outlet pressure to provide n even the main burner gas flow. To check for gas pipe leaks, put soap on the pipe connecting to the valve, if it bubbles, it means there's leakage. Cycle the main burner several times, allowing at least 30 seconds between cycles for the regulator to resume the step function. If desired outlet pressure or flow rate cannot be achieved by adjusting the gas control, check the inlet pressure using a manometer at the inlet pressure tap or upstream of the gas control.
